Description for Silica Insulating Bricks

Silica Insulation Bricks are produced with silica through adding inflammable substances such as coke, anthracite coal, sawdust, and carbonized rice husk, or foaming agents to form porous structure. Generally add 35-45% anthracite coal or 30% coke as inflammable substances. Since there are Fe2O3 and Al2O3 in the ash of coke and anthracite coal, there is no need to add iron scales. Silica Insulation Brick’s main mineral composition includes 78%~86% tridymite, 13%~15% cristobalite and 4%~7% quartz. Its cold crushing strength is 2.0-5.9MPa, thermal conductivity is 0.35-0.42W/(m•K) and density is 0.9-1.1g/cm3.
